HMC744LC3C Functional Diagram

General Description

The HMC744LC3C is a 1:2 Fanout Buffer designed to support data transmission rates up to 13 Gbps, and clock frequencies as high as 13 GHz. The HMC744LC3C also features an output level control pin, VR, which allows for loss compensation or for signal level optimization.


All input and output signals to the HMC744LC3C are terminated with 50 Ohms to Vcc on-chip, and may be either AC or DC coupled. Inputs or outputs can be connected directly to a 50 Ohm to Vcc terminated system, while DC blocking capacitors may be used if the terminating system is 50 Ohms to ground. The HMC744LC3C operates from a single +3.3V DC supply, and is available in a ceramic RoHS compliant 3x3 mm SMT package.
